[0001] The utility model relates to the technical field of electrocardiograms, in particular to an anti-interference electrocardiogram lead wire for high-definition signal transmission. Background Art
[0002] Electrocardiogram is a technology that uses an electrocardiograph to record from the body surface the changes in electrical activity produced by the heart during each cardiac cycle. The heart generates weak bioelectric current when it contracts and relaxes, which can be transmitted to the surface of the human body and displayed through the electrocardiogram.
[0003] With regard to the existing related technologies, the inventors believe that the following defects often exist: when the existing ECG lead wires are connected to the ECG machine, they are usually directly inserted into the corresponding interface through a plug, which makes it easy for the lead wires to be accidentally touched when the patient moves or the surrounding environment changes slightly, thereby causing the lead wires to accidentally fall off the ECG machine, which may not only interrupt the ECG monitoring, but also affect the accuracy and timeliness of medical diagnosis. Utility Model Content
[0004] The technical problem to be solved by the utility model is that the existing technology has the disadvantage that the lead wire is easily touched by mistake when the patient moves or the surrounding environment changes slightly, which leads to the lead wire accidentally falling off the electrocardiograph. For this reason, we propose a high-definition signal transmission anti-interference electrocardiograph lead wire.
[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a high-definition signal transmission anti-interference ECG lead wire, including an electrocardiograph, a plug is installed on one side of the electrocardiograph, one end of the plug is fixedly connected to an anti-interference high-definition transmission line, two card blocks are fixedly connected to one side of the electrocardiograph, a storage groove is opened inside the plug, two connecting plates are slidably connected inside the storage groove, a limit rod is fixedly connected to the outer side of the connecting plate, and the surface of the limit rod is slidably connected to the inside of the card block.
[0006] Preferably, an elliptical block is rotatably connected inside the storage groove, one side of the elliptical block is fixedly connected to a connecting rod, a knob is installed on the inner side of the connecting rod, and a thrust spring is fixedly connected to the outer side of the connecting plate, and the other end of the thrust spring is fixedly connected to one side inside the storage groove.
[0007] Preferably, a telescopic rod is slidably connected inside the connecting rod, one end of the telescopic rod is fixedly connected to one side of the knob, a limiting groove is provided on one side of the plug, and one side of the knob is fixedly connected to a limiting block.
[0008] Preferably, one end of the telescopic rod is fixedly connected to a tension spring, and the other end of the tension spring is fixedly connected to one side inside the connecting rod.
[0009] Preferably, both sides of the connecting rod are provided with limit sliding grooves, and both sides of the telescopic rod are fixedly connected with limit sliding blocks.
[0010] Preferably, first sliding grooves are provided on both sides of the storage groove, and first sliding blocks are fixedly connected to both sides of the connecting plate.
[0011] Preferably, the difference between the maximum diameter and the minimum diameter of the elliptical block is greater than the distance that the limiting rod is inserted into the interior of the clamping block.
[0012] Technical effects and advantages of the utility model:
[0013] In the utility model, after the user inserts the plug into one side of the electrocardiograph for connection, the user moves the position of the limit rod so that the limit rod enters the interior of the clamping block to limit the plug, thereby making the connection between the plug and the electrocardiograph more stable and preventing the plug from falling off the electrocardiograph due to accidental contact with the anti-interference high-definition transmission line.

DETAILED DESCRIPTION
[0019] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0020] Reference Figure 1 and Figure 2As shown, the utility model provides a technical solution: a high-definition signal transmission anti-interference electrocardiograph lead wire, comprising an electrocardiograph 1, a plug 3 is installed on one side of the electrocardiograph 1, one end of the plug 3 is fixedly connected with an anti-interference high-definition transmission line 2, one side of the electrocardiograph 1 is fixedly connected with two clamping blocks 6, a storage groove 7 is provided inside the plug 3, two connecting plates 8 are slidably connected inside the storage groove 7, a limiting rod 9 is fixedly connected to the outer side of the connecting plate 8, and the surface of the limiting rod 9 is slidably connected to the inside of the clamping block 6. After the user inserts the plug 3 into one side of the electrocardiograph 1 for connection, the limiting rod 9 is moved so that the limiting rod 9 enters the inside of the clamping block 6 to limit the plug 3, so that the connection between the plug 3 and the electrocardiograph 1 is more stable, and the plug 3 is prevented from falling off from the electrocardiograph 1 due to accidental contact with the anti-interference high-definition transmission line 2.
[0021] Reference Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment: an elliptical block 10 is rotatably connected inside the storage groove 7, a connecting rod 11 is fixedly connected to one side of the elliptical block 10, a knob 12 is installed on the inner side of the connecting rod 11, and a thrust spring 19 is fixedly connected to the outer side of the connecting plate 8, and the other end of the thrust spring 19 is fixedly connected to one side inside the storage groove 7. The difference between the maximum diameter and the minimum diameter of the elliptical block 10 is greater than the distance that the limiting rod 9 is inserted into the inside of the card block 6. After the user inserts the plug 3 into the inside of the electrocardiograph 1, the elliptical block 10 is driven to rotate by rotating the knob 12, and the connecting plate 8 is pushed to move to both sides, so that the limiting rod 9 enters the inside of the card block 6 to limit the plug 3. When the anti-interference high-definition transmission line 2 needs to be disassembled, the elliptical block 10 is driven to rotate by rotating the knob 12 to release the limit on the connecting plate 8. Under the thrust of the thrust spring 19, the connecting plate 8 is pushed to move toward the middle, so that the limiting rod 9 is separated from the inside of the card block 6.
[0022] Reference Figure 4 As shown, in this embodiment: the interior of the connecting rod 11 is slidably connected with a telescopic rod 13, one end of the telescopic rod 13 is fixedly connected to one side of the knob 12, a limiting groove 14 is provided on one side of the plug 3, and a limiting block 15 is fixedly connected to one side of the knob 12. The user rotates the knob 12 to drive the limiting rod 9 to enter the interior of the block 6. After fixing the plug 3, the knob 12 is pressed to make the limiting block 15 enter the interior of the limiting groove 14, to limit the angle of the knob 12, to prevent the knob 12 from rotating due to vibration, causing the limiting rod 9 to detach from the interior of the block 6.
[0023] Reference Figure 4As shown, in this embodiment: one end of the telescopic rod 13 is fixedly connected to a tension spring 16, and the other end of the tension spring 16 is fixedly connected to one side inside the connecting rod 11. By installing the tension spring 16 at one end of the telescopic rod 13, continuous tension can be released on the telescopic rod 13 to prevent the knob 12 from being displaced by vibration, causing the limit block 15 to disengage from the inside of the limit groove 14.
[0024] Reference Figure 4 As shown, in this embodiment: limiting grooves 17 are provided on both sides of the connecting rod 11, and limiting sliders 18 are fixedly connected on both sides of the telescopic rod 13. When the user pulls the knob 12 to release the limit on the knob 12, the limiting sliders 18 on both sides of the telescopic rod 13 limit the movement of the telescopic rod 13 to prevent the telescopic rod 13 from escaping from the inside of the connecting rod 11.
[0025] Reference Figure 2 As shown, in this embodiment: first slide grooves 20 are opened on both sides of the storage groove 7, and first sliders 21 are fixedly connected on both sides of the connecting plate 8. When the user turns the knob 12 to drive the connecting plate 8 to move, the first sliders 21 on both sides of the connecting plate 8 move inside the first slide grooves 20 to assist the movement of the connecting plate 8 and prevent the connecting plate 8 from tilting and causing movement jamming.
[0026] Working principle: After the user inserts the plug 3 into one side of the electrocardiograph 1 for connection, the user moves the position of the limit rod 9 so that the limit rod 9 enters the interior of the card block 6 to limit the plug 3, making the connection between the plug 3 and the electrocardiograph 1 more stable, and preventing the plug 3 from falling off the electrocardiograph 1 due to accidental contact with the anti-interference high-definition transmission line 2. After the user inserts the plug 3 into the interior of the electrocardiograph 1, the user rotates the knob 12 to drive the elliptical block 10 to rotate, pushes the connecting plate 8 to move to both sides, so that the limit rod 9 enters the interior of the card block 6 to limit the plug 3. When the anti-interference high-definition transmission line 2 needs to be disassembled, the knob 12 is rotated to drive the elliptical block 10 to rotate to release the limit on the connecting plate 8. Under the thrust of the thrust spring 19, the connecting plate 8 is pushed to move toward the middle, so that the limit rod 9 is disengaged from the interior of the card block 6, and the knob 12 is rotated to drive the limit rod 9 to enter the interior of the card block 6. After the plug 3 is fixed, the knob 12 is pressed to make the limit block 15 enter the limit groove 14 to limit the angle of the knob 12 to prevent the knob 12 from rotating due to vibration, causing the limit rod 9 to disengage from the inside of the block 6. By installing a tension spring 16 at one end of the telescopic rod 13, a continuous tension can be released on the telescopic rod 13 to prevent the knob 12 from being displaced due to vibration, causing the limit block 15 to disengage from the inside of the limit groove 14. In the process of pulling the knob 12 to release the limit on the knob 12, the limit sliders 18 on both sides of the telescopic rod 13 limit the movement of the telescopic rod 13 to prevent the telescopic rod 13 from disengaging from the inside of the connecting rod 11. In the process of rotating the knob 12 to drive the connecting plate 8 to move, the first sliders 21 on both sides of the connecting plate 8 move inside the first slide groove 20 to assist the movement of the connecting plate 8 to prevent the connecting plate 8 from tilting.
[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
